Eved: [RFM] wifi0: RB won't change from Ch.104 to Ch.112 (warn-only).

Question

SmartSelect is running on both 7731's that are bridging network and voice traffic to an office across the street. Every now and then traffic stops passing over the bridge.

The 7731's have been installed for three months and the channel has never moved from channel 104............

Eved: [RFM] wifi0: RB thinks Ch.104 is not optimal.  Best available is Ch.112. Reason: non-blacklisted channel found

Eved: [RFM] wifi0: Interference detected: nf1hi: -69 > -75, nfcap1hi: -69 > -75,  badness=1

Your NRBs will follow any channel change by your Root Bridge.

Michael - what commands should we give to the NRB in this situation as we see this error a lot.

michael_brado · Answer

Smarty, the SmartSelect agorithm on 7731s *will* change channels, if you want it to.

The default behavior is (warn-only), but you can type this CLI command after SSH to your RB:

rkscli:
rkscli: get version
Ruckus Wireless 7731 Wireless Bridge
Version: 9.2.0.0.174
OK
rkscli:
rkscli: get blacklist wifi0
wifi0 Channel Blacklist is warning only.
wifi0 Threshold override:
OK
rkscli:
rkscli: set blacklist wifi0 enable
OK
rkscli:
